Looks like the best rounds are the 200/4.7 or the 230/3.7. I know this is out of a 4” gun but rules state that you need to shoot it out of a 5”. I’ll get more fps out of a 5” but it’s gonna be hard to find a 5” revolver for IDPA to chrono, so I’ll stick with the 230/3.7 load. That way I can keep my 200gr rounds for my Kimber 1911 in the CDP division and 230gr rounds for my S&W 625 in the ESR Division.
